GAS BURNER.

This invention relates to a gas burner and aims to provide a device of this character which is of simple and durable construction, economical in its consumption of fuel, efficient in the generation of heat, and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside in certain 110\'6l features of the'construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming a part of this specification, and in which Figure l is a sectional view showing a burner embodying the present invention set up in a furnace,

Figure 2 is a view in horizontal section on the line 22 of Figure 1, parts being shown in elevation for the sake of illustration, and

Figure 3 is a fragmentary perspective view of the tip of one of the burner pipes.

Referring to the drawings it will be seen that the furnace structure is illustrated diagrammatically and includes a body 1 which may be of any suitable type. In the firebox of the furnace the burner, designated generally at 2, and constituting the present invention, is provided. The burner 2 includes an air chamber consisting of an outer cylindrical body 3 with which an air pipe 4: connects, the air pipe 4 extending into the open lower end of the body 3. The upper end of the body 3 is closedby means of an end wall 5. VVithin't-he body 3 acup-shaped gas-receiving chamber 6 is provided and is made up of a cylindrical wall 7 arranged in spaced concentric relation to the cylindrical wall 3, and a bottom or lower wall 8. The upper end of the chamber 6 is closed by the central portion of the top wall 5 to which it is suitably fastened.

A gas supply pipe 9 extends through the air supply pipe 4 and is connected to the bottom wall 8 of the gas chamber 6.

The cylindrical wall 7 of the gas chamber 6 is provided with a circular series of jet openings 10 from which the gas issues in the form of jets. These jet openings 10 and the jets which issue therefrom are radially disposed as will be understood from an inspection of Figure 2. A burner pipe 11 is radially aligned with each. jet'opening 10, the burner pipes being carried by the cylindrical wall 3 of the air chamber and having their inner ends in open and direct communication with the air space 12 of the air chamber. The outer ends of the burner pipes carry tips 13 having outlet orifices 14 located to discharge angularly directed jets J of the commingled air and fuel so that the flames produced when the jets J are burning will intersect and commingle, as shown in Figure 2. I

In operation air and gas are supplied through the pipes 4 and 9, respectively, and if desirable the air and gas may be supplied under pressure. The gas issues in the form of jets from the jet openings 10 and these jets traverse the air space 12 and entrain the air supplied thereto from the air supply pipes 4. The entrained air and the gas pass into the burner pipes 11 wherein they are completely commingled to produce a highly combustible mixture which issues from the outlet orifices 12 to provide the jets J which are ignited to produce a flame of intense heat. flames are distributed entirely around the firebox so that the furnace or boiler is uniformly heated.

I claim:

A burner comprising an air chamber, a

gas chamber within the air chamber, means for supplying air to the chamber, meansfor supplying gas to the gas chamber, horizontal burner pipes carried by the gaschamber and having tips, each tip being provided with two outlet orifices, the inner ends of the burner pipes being open and in direct communication with the interior of the air chamber, the gas chamber having jet openings aligning with the burner pipes, whereby the jets issuing from the jet openings entrain the air and carry it into the burner passages, said burner pipes being arranged in circular series and having the outlet orifices of their tips angularly disposed to provide for intersecting ets of combustible fuel, each tip supplying jets that take part in the formation of two flames.
